The best USB flash drives make it a breeze to bring your most important files with you everywhere you go but they can also be useful for when you need to move large files from one computer to another.

The Kingston IronKey Keypad 200 isn't your ordinary flash drive as you can probably tell from the picture above. Instead of just plugging the drive into your computer to access the files stored on it, you first need to put in a PIN code using its keypad. While this may be overkill for some, those looking to securely transport their most sensitive files will likely appreciate both the design and functionality of the Kingston IronKey Keypad 200.
Besides needing to enter a pin to unlock it, the Kingston IronKey Keypad 200's circuits are coated with tamper-evident, tough epoxy to prevent others from examining the drive's circuitry without damaging it.

How to choose the best USB drive for you
When buying a USB flash drive, you’ll want to focus on storage first. If you have a large number of files, videos, or songs you want to carry around with you, getting a USB drive with at least 64GB is critical. Most USB flash drives go up to 256GB and a few now have 1TB versions.
However, if you’re more concerned about getting a cheap memory stick for carrying a few files, you can probably get by with 16GB or 32GB of storage space.
Aside from this, you’ll also want to consider other critical features, such as read/write speeds. The faster the speed, the more data you can write to the drive quickly and access what you’re trying to see. That’s why we look for USB 3.1 support or at least, USB 3.0 support if you care about performance.
You can tell if a USB flash drive supports USB 3.0 or higher if its connector is colored blue. Most USB-C drives support USB 3.0 by default.
Another factor to consider is design. Flash drives aren’t the hottest or coolest devices but they come in a variety of shapes and sizes. In terms of durability, look for USB drives with shock-proof or waterproof designs and other features that limit the chances of your drive being damaged.
Last but not least, check the warranty on a USB flash drive; a lifetime warranty is preferred but 5 years is a decent fallback option.
USB types explained
As mentioned earlier in this guide, there are a number of different USB types and protocols that you need to be aware of before buying a USB drive.
USB-A vs. USB-C
The first and probably most important you need to know about is USB-A vs. USB-C. While our USB-C vs. USB-A explainer goes into more detail, USB-A is the older variety with a larger, rectangular connection plug that can only be inserted into a port one way. USB-C is newer and has a much smaller, oval-shaped plug that’s reversible. However, you’ll also want to check out our Thunderbolt vs. USB4 guide.
USB 2.0, USB 3.0, USB 3.1, USB 3.2 and USB 4.0
The number after USB indicates the version of USB that is used by a particular device. Older generations have lower numbers as well as slower transfer speeds. If you don’t need the fastest USB drive around, you can save a bit by opting for a USB 2.0 or USB 3.0 drive but it will take longer to transfer files onto and off of the device.
USB 3.0: Up to 5 Gbps
USB 3.1: Up to 10 Gbps
USB 3.2: Up to 20 Gpbs
USB 4.0: Up to 40 Gbps (only available on USB-C devices)
